You can track the growth of the number and nature of OA policies inROARMAP and the growth in the number and size of IRs in ROAR.

Comment: thanks, Stevan. The progress on OA mandates is important, and remarkable indeed!

It would be wonderful to have the exact number of open access articles, to assess growth in OA via self-archiving. I'll be looking into the ROAR data for the next Dramatic Growth update. Comments and suggestions for the best indicator(s) of growth of OA articles are most welcome. The ideal would be a single indicator, whether it is total OA articles or best estimate - or, a very few indicators.
